I wanted to start a post for people to coordinate working on this achievement.

The reward is either Heroic AA or a pretty spectacular augment:

Relife Adornment

Caster version

There are several different versions.

So I'm going to post what I've done and what I need to finish this in the hopes that others will do the same and we can get this accomplished for a number of people.
